Researcher argues Bayesian stats is the only principled way to analyze small-sample Likert data

HCI researcher Ian Arawjo updated his chapter on analyzing HCI study data to cover three statistical philosophies: frequentist, estimation stats, and Bayesian stats. He argues the only consistent, principled way to handle small-sample Likert data is Bayesian — but that requires overhauling one's entire statistical approach. His takeaway: both estimation and Bayesian methods have usability problems, with estimation's being subtler.
